1-Eth-oxy-methyl-5-methyl-9-phenyl-6,7,8,9-tetra-hydro-1H-pyrimido[4,5-b][1,4]diazepine-2,4(3H,5H)-dione.

ABSTRACT: The title compound, C(17)H(22)N(4)O(3), comprises a 1,4-diazepine ring in a twist-boat conformation fused to a pyrimidine ring. The dihedral angle between the pyrimidine and phenyl rings is 80.8?(1)°. The crystal packing features N-H?O and C-H?O hydrogen bonds.
